I have a PDF which has a required field and a submit button.
I was able to write a simple script to prevent the user from submitting if the required field is not filled.
xfa.host.messageBox("Please fill the required field");
xfa.event.cancelAction = true;
Above script works fine with Acrobat Reader 9 but I ran into a problem with Acrobat Professional 7.
The message box pops up but the next 2 lines don't work.
Is there a way to achieve this regardless of Acrobat versions?
